I have been using this regex for checking urls.

((?:href|src)=["']?)?((https?:\/\/(?:www\.)?|www\.)[a-z0-9][^@]*?)(?=&quot;|&#x27;|&lt;|[\s"'<]|$)

However, this matches urls enclosed in brackets Ex: (www.x.xom) (according to the regex, only the end bracket because there are cases where there are brackets inside a url). How do I write a regex so as to ignore the outer enclosing brackets??

Strings to be matched: (www.xyz.com) - only the url and www.xyz.com?query=(abc) - the entire string and (www.abc.com?q=(params)) - the string enclosed. Existing regex has a fault where if the string is (www.xyz.com) - it matches www.xyz.com).

To clarify: you want to match _any_ URL, excluding any enclosing brackets/parentheses? Can you give us some example matches? – qxz Jan 27 '17 at 17:34
Sure. Strings to be matched: (www.xyz.com) - only the url and www.xyz.com?query=(abc) - the entire string and (www.abc.com?q=(params)) - the string enclosed. Existing regex has a fault where if the string is (www.xyz.com) - it matches www.xyz.com). Thanks – Mohan Krishnan Jan 27 '17 at 17:49
(You should [edit your question](http://stackoverflow.com/posts/41899748/edit) instead of commenting.) Looks like you should look into matching _balanced parentheses_ with regex. – qxz Jan 27 '17 at 18:02
Yup. Any suggesstions on how to proceed. – Mohan Krishnan Jan 27 '17 at 18:06
Why are you checking a URL? – Jan 27 '17 at 18:35
to add a hyperlink to it – Mohan Krishnan Jan 27 '17 at 19:11

I would just check, if the first character is `(` and the last character is `)` instead of creating a complicated regex. – ssc-hrep3 Jan 27 '17 at 19:30
That'll work, but i just want to know, how it can be done in regex?. – Mohan Krishnan Jan 27 '17 at 19:39
